Question

Solve for x. 9x = 3x − 36

Answer 1

Answer: $x=-6$

Step-by-step explanation:

In order to solve for "x", we must remember the following properties:

• The Subtraction property of Equality states that:

        If $a=b$, then $a-c=b-c$

• The Division property of Equality states that:

         If $a=b$, then $\frac{a}{c}=\frac{b}{c}$

Therefore, knowing these properties, we can solve for "x" to find its value.

First, we need to subtract $3x$ from both sides of the equation. Then:

$9x-(3x) = 3x - 36-(3x)\\\\6x=-36$

And finally, we can divide both sides of the equation by 6. Then we get:

$\frac{6x}{6}=\frac{-36}{6}\\\\x=-6$

Answer 2

Answer: x= -6

Step-by-step explanation:

The given equation : $9x = 3x- 36$

To solve for x , We first subtract 3x from both the sides m, we get

$9x-3x = 3x-36-3x$

Now, Simplify

$6x = -36$

Divide both sides by 6 , we get

$\dfrac{6x}{6}=\dfrac{-36}{6}$

Now, Again Simplify

$x=-6$

Hence, the value of x in the given equation is x= -6
